Problems solved by technology

This may cause an absence of image data in regions for which there is depth data and / or an absence of depth data in regions for which there is image data.
Decreased resolution requires less computation, which speeds up processing.
This may result in failed barcode decoding.
If the ambient light is not sufficient, the target is dark, or black, and the passive stereo vision system may then fail to provide 3D data.

Embodiment Construction

[0012]An aspect of the specification provides a method that includes acquiring a two-dimensional (2D) preview image of an object, where the 2D preview image is obtained from a 2D camera device. The method also includes processing the 2D preview image to determine a location of a code on the object. As described in more detail herein, the code may be a barcode. The method also includes acquiring a three-dimensional (3D) image of the object, where the 3D image is obtained from a 3D camera device. The method also includes processing the 3D image to determine depth data. The method also includes acquiring a 2D data capture image of the object based on the depth data in the processed 3D image, where the 2D data capture image captures the code, and where the 2D data capture image is obtained from the 2D camera device. The method also includes reading the code based on the 2D data capture image.

[0013]In some implementations, the 3D camera device may be an infrared camera device. In some im...

Abstract

Implementations relate to a device and method for barcode scanning and dimensioning. In some implementations, the method includes acquiring a two-dimensional (2D) preview image of an object, and processing the 2D preview image to determine one or more dark areas and to determine a location of a code on the object. The method also includes acquiring a three-dimensional (3D) image of the object based on the one or more dark areas, and processing the 3D image to determine depth data and to determine dimensions of the object. The method also includes acquiring a 2D data capture image of the object based on the depth data in the processed 3D image, where the 2D data capture image captures the code. The method also includes reading the code based on the 2D data capture image.

Description

BACKGROUND[0001]Accurate measurement of packages prior to shipping is an important task in the transportation and logistics industry. Dimension measurements and weight measurements are common measurements prior to shipping a package. Another common task prior to shipping is the scanning of barcodes. Barcode scanning is generally accomplished using imaging scanners, where an imaging scanner takes a picture of the entire barcode, and a processor running image-processing algorithms recognizes and decodes the barcode. Barcode scanning is often implemented on a mobile device.BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS[0002]The accompanying figures, where like reference numerals refer to identical or functionally similar elements throughout the separate views, together with the detailed description below, are incorporated in and form part of the specification, and serve to further illustrate implementations of concepts described herein, and explain various principles and advant...
